The World's best I/O-relays for over 40 years


Aiming to build the best I/O-relays in the World

Delcon has been manufacturing solid state relays for over 40 years. We have built a global distribution network of 40 countries, where you can obtain our relays locally and customer service can be provided in your own language.

We work for culture of integrity and ethical working environment. We take into account our ecological footprint in our production and development. Read about our values and principles here Code of Conduct.

Delcon relays' high quality is assured by management's full commitment to follow high quality standards in every step in our daily work. The same commitment we demand from all of our employees.


Save when choosing relays

Save Money

The cost of replacing relays is often greater than the price of the relays being replaced. Our products can help you reduce maintenance costs and improve output capacity utilization. You’ll also avoid costs arising due to interruptions.

Even on the basis of relay changeover costs alone, Delcon relays work out more economically. To clarify this, we’ve worked out how much you can save if the calculations also include the profits lost due to interruptions (click here).

Long lifespan

Effortless Years

Delcon relays have many times longer life-time than other relays in terms of comparable MTTF (Mean Time To Failure) values. In other words they last as long as your automation system without painstaking production stops and pointless replacing of broken relays.
